May you post the idea in LuCI github. commas is actually hack injecting working value into firewall, probably should be proper list in place of option.

Just FYI - the underlying system/OS can only do 1 range per rule. Most OSes are the same.
Not sure that matters to the OP, but may cause confusion for various layers of abstraction needed to conceive the OPs request.
It needs new abstraction, both iptables and nftables take comma-separated ad-hoc address ranges which successfully pass through from malformed config.
